App Hanging on Actions.[key]/Actions.pop()

[iChaosren]

Version

• react-native-router-flux v4.0.0-beta.28
• react-native v0.51
• expo v24

Expected behaviour

I use Actions.pop() on the Lightbox Component.
Lightbox Scene Disappears.

Actual behaviour

Click on Below Component:

class MovieListRightHeader extends Component {
    render() {
        return (
            <TouchableOpacity onPress={() => {
                Actions.filterModal();
            }}>
                <Text>Filter</Text>
            </TouchableOpacity>
        );
    }
}

Following Router gets used:

const RouterComponent = () => {
    return (
        <Router navBar={NavBar} createReducer={reducerCreate} sceneStyle={{ backgroundColor: '#1d1d1d' }}>
            <Lightbox key="lightbox">
                <Stack key="root">
                    <Scene key="movieList" component={MovieList} title="Movies" left={<MovieListLeftHeader />} right={<MovieListRightHeader />} initial />           
                </Stack>
                <Scene key="error" component={Error} />
                <Scene key="filterModal" component={FilterModal} />
            </Lightbox>
        </Router>
    );
};

Scene Displays as expected.
Click on Close Button.
App hangs and eventually closes.

export default class FilterModal extends Component { 
  render() {
    return (
    <Button onPress={() => Actions.pop()} title="Test Test Test" />
    );
  }
}

Logs the moment I tap on the MovieListRightHeader button:

5:44:13 PM
ACTION: Object {
  "params": Object {
    "cardStyle": Object {
      "backgroundColor": "#1d1d1d",
    },
    "init": true,
    "navBar": [Function NavBar],
    "routeName": "filterModal",
  },
  "routeName": "filterModal",
  "type": "REACT_NATIVE_ROUTER_FLUX_PUSH",
}
5:44:13 PM
ACTION: Object {
  "routeName": "movieList",
  "type": "REACT_NATIVE_ROUTER_FLUX_BLUR",
}
5:44:13 PM
ACTION: Object {
  "params": Object {
    "cardStyle": Object {
      "backgroundColor": "#1d1d1d",
    },
    "init": true,
    "navBar": [Function NavBar],
    "routeName": "filterModal",
  },
  "routeName": "filterModal",
  "type": "REACT_NATIVE_ROUTER_FLUX_FOCUS",
}

NOTE: I've tried simply navigating instead to any page, even one I just created and it hangs.

Turns out, using the createReducer function can cause some... Issues...
